Use a Photoresistor (a sensor that changes resistance based on light) to read the brightness of the room. If it gets dark (value below 500), an LED turns on. If it's bright (value above 500), the LED turns off.

You’ve felt the spark. Maybe you watched a YouTube video of a homemade robot scuttling across a desk, or perhaps you want to repair a broken lamp instead of throwing it away. The world of electronics is fascinating, but for a complete beginner, it can also be intimidating. Resistors, capacitors, diodes, breadboards—the jargon alone is enough to make your head spin.

You attach a small Electret Microphone module (or a simple piezo disc) to an analog pin. When you clap, the sound wave causes a voltage spike. Your code detects that spike and toggles an LED or a relay (for a lamp).
